CoVs use different human receptors as points of entry: SARS‐CoV‐1, SARS‐CoV‐2, and HCoV‐NL63 use angiotensin‐converting enzyme 2 (ACE2); 14 , 15 , 16 MERS‐CoV uses dipeptidyl peptidase‐4 (DPP4); 17 CoV‐22E uses aminopeptidase N; 18 and HCoV‐OC43 as well as HCoV‐HKUI use O‐acetylated sialic acid (see Table 1).
